Driver callback routine when panic() is called

[Pinyowattayakorn, Naris]

Hi folks,

I don't know if this is an appropriate question to ask on this mailing list
but I have no idea where to ask. 

Is there any call that can be used for a driver to register system crash
callback routines. Thus, If panic( ) is called, such a callback can save
device-state information to be written into the system crash dump file. 

Thanks,
Naris
